JOSEPH CHARLES HOVELLS, OF MADISON, VISCONSIN.

NOZZLE FOR FIRE-ENGINES.

Specification Vof Letters Patent No. 28,865, dated June 26, 1860.

To all whom it may concern.'

Be it known that- I, JOSEPH CHARLES HowELLs, of Madison, Dane county,and State of lVisconsin, have invented a new and Improved lVIethod ofOperating Adjustable Nozzles for Fire-Engine Hose-Pipes, &c.; and I dohereby declare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, figures, andletters of reference thereon, making part of this specification.

Of the said drawings Figure l is a front elevation; Fig. 2, is alongitudinal section and Fig. 3, is a transverse section of the same.

Similar letters of reference indicate like parts in all the drawings.

The nature and object of my invention is to render a nozzle instantlyadjustable and thus enable the person having control of the pipe todischarge such a sized stream of water as may be desirable under thecircum stances.

To enable others skilled in the art to make and use my invention I willdescribe its construction and operation.

A represents a pipe of the desired material having a screw F cut thereinto connect with the hose.

B B, are the adjustable mouth pieces which are made of composition brassor other noncorrosive material and secured toable mouth pieces B B, andwhich serve to adjust the size of the opening as plainly shown in allthe iigures. The adjustable pieces B B are secured at (a a) by means ofa small collar as seen in Fig. 2.

F is a cap or shield with a milled or roughened edge concentricallycountersunk on the underside and corresponding to the concentric groovesE E so as to admit of the movement of the collar C as seen by the dottedlines in Fig. l, and attached to the collar C by the screws Z d.

The operation will be as follows: The pipe or nozzle being secured tothe hose and the adjustable pieces B B set to describe a circle which isdone by rotating the collar C in the direction of the arr'ow and theperson holding the pipe desiring to make a larger or wider opening hasonly to turn the collar in a reverse direction and the opening in thenozzle is instantly adjusted to the capacity desired.

To remove the adjustable pieces B B it is only necessary to take out thepins or screw heads (c c) as will be readily perceived by any oneskilled in such arts.

Having thus described my improved adjustable nozzle I will state what Idesire to secure by Letters Patent.

I do not claim the adjustable mouth pieces B B nor the pipe A as theyare already well known and have been and are now used for a variety ofpurposes; but

I claim- The arrangement and combination of the rotary collar C, cap F,the ears b the pins or screw heads c c, with the adjustable mouth piecesB B, substantially as and for the purposes herein set forth anddescribed.

JOSEPH CHARLES HoWELLs. [L s.]
